SOLE-LAYING MACHINE.

SPECIFICATION formingpart` of Letters Patent No. 376,406, dated January 10, 1888.

Application filed October 10,` 1887. Serial No. 251,941. (No model.)

To @ZZ whom, it may concern:

Be it known that I, FREDERICK W. CoY, of Boston, in the county of Suffolk and State of Massachusetts, have inventedcertain new and useful Improvements in Solo Laying or Pressing Machines, of which the following is aspeciiication.

This invention relates, particularly, to machines for pressing cement-coated louter soles against lasted uppers of boots and shoes and holding the soles against the uppers while the cement is setting or hardening; and it Vhas for its object, tirst, to provide certain improve; ments in the sole-presser, whereby displacement of the sole by the first Contact of the presser therewith is prevented and the sole is grasped and held at its shank portion before the forepartand heel portions come in con` tact with the presser.

. The invention also has for its object to prof vide certain improved mechanism in an organized machine, either forsolelayng or for beating out or leveling soles, whereby a series of jacks moving in a. circular path are pressed upwardly against'corresponding presses during the greater part of a complete revolution and depressed during the remaining part of said revolution.

To these ends my invention consists in the several improvements which I will now proeeed to describe and claim.

Ot` the accompanying drawings, Vforming a part of this specification, Figure l represents a vertical central section of a sole-laying Inachine embodying my invention. Fig. 2 represents a side elevation ot' a portion ot' the machine, showing one' of the sole-pressers in section. Fig. 3 represents a vertical section on line x x', Fig. 2. Fig. 4 represents a top view. Fig. 5 represents a horizontal section on line y y, Fig. l.

The same figures and letters of reference indicate the same parts in all the figures.

In carrying out my invention I provide a verticalcircular standard, 2, supported by a suitable base, andy mount on said standard two horizontal heads or frames, 3 4which are rigidlyI connected by vertical tie-rods and are adapted to rotate freely on the standard 2, said heads and their connecting-rods constituting a rotary carrier. f

Secured rigidly to the upper head, 3, are a series of standards, -in this easesixin number-at equal distances apart. Said standards support the sole-pressers P, the construction of which will be more fully described hereinafter, there being one presser P for each standard. Below the presser P are a corresponding series ofjaeks, J, each adapted to support a last, L, and present said last, with an upper thereoxrand a cement-coated sole, to the corresponding presser, there being a jack for each presser. Each jack is composed of an angulararm, 30, having a dovetail rib or guide, 3l, on its upper portion and standards 28 and 29, secured by screws to said guide and adjustable thereon, said standards being provided, respectively, with a toe-rest andwith a spindle to enter the spindle-socket of the last L. The arm 30 is pivoted at 32 to ears on a slide, 33, which is adapted to move vertically in a vertical guide or socket, 5l, formed on the base of the standard 5 above it, said socket projecting downwardly through an opening in the head 3. The slide 33 is enlarged at its upper end to form a support for the upper .portion of the arm 30 when the jack is in position under the presser which it accompanies, as shown at the right of Fig. 1. The pivotal connection of the arm 30 to the slide 33 enables the jack to be swung out from under the accompanying presser, as shown at the left of Fig. 1, to enable the operator to conveniently unjack and jack the shoe and place the cement-coated outer sole thereon.

The slide 33 is pivotcd by a bolt, 36, to the upper ends of two links, 34 34, the lower ends of which are pivoted to two similar links, 35 35, which in turn are pivoted at 37 to the t lower head, 4. The 'links 34.and 35 constitute toggle-joints, which support and elevate the slide 33 and the jack thereon, as presently described. The meeting ends of the links 34 35 of each pair are connected with the links ICO an ear on the head 4, againstahorizontal cam, 39, which is rigidly attached to the supportin g-standard 2. Said cam or endless track has a recess at one side of its periphery,while the greater portion of its periphery is concentric with the standard 2, as shown in Fig. 5. 4When the roll 3S enters the recessl of the cam, the toggle-jointlinks are thrown out of alignment, and the slide 33 and the jack supported thereby are depressed, as shown at the left of Fig. 1; but when the roll 3S reaches the concentric portion of the cam the toggle-joint links are thrown into alignment, or nearly so, and the slide 33 and its jack are raised and pressed against the corresponding solcpresser7 as shown at the right of Fig. 1.

It will be seen from the foregoing description and by reference to the drawings that when the heads 2 3 are rotated the series of jacks and their supporting devices and the correspond ing sole-pressers are moved in a circular path, and that at a given point in said path-viz., that where the recess of the cam 39 is locatedeach jack and its support will be lowered from the accompanying presser by the action of the spring 40, which causes the wheel 3S to enter the cam-recess, and thus throws the toggle links out of alignment. Vhen the jack is lowered, it may be swung out of position, as above described, to permit the removal of the shoe from thejack and the application of another shoe, and then swung back to position.

It will also be seen that each jack is raised after its depression by the movement of the camroll of its supporting-toggle onto the concentric portion of the cam 39, so that each jack during the greater part of its revolving movement is held up against the corresponding sole-presser, and is depressed only at the operators station. The connected heads 3 4 and thejacks and solepressers carried thereby are impelled by a driving-shaft, 43, having a bevel-pinion, 42, meshing with a bevel-gear, 41, formed on or rigidly attached to thehead 4. Motion is imparted to the shaft 43 by a driving-pulley, 44, thereon. Said pulley is normally loose on the shaft 43 and has a clutch on its hub adapted to engage a clutch, 45, which is engaged with the shaft so as to rotate therewith,butis free to slide thereon, and is normally engaged with the clutch on the driving-pulley by a spring or springs, 53, Fig. 1. rllhe sliding clutch is automatically disengaged from the driving-pulley by a pin, 46, which slides vertically in fixed guides and is pressed upwardly by a spring, so that it bears on a camshaped collar, 54, on the clutch 45, and by contact with said cam forces the said clutch back out of engagement with the driving-pulley, as shown in Fig. 1, once during a complete rotation of said clutch. The parts are so timed that the clutch 45 is thrown out and the rotation of the shaft 43 stopped when a cam-roll, 3S, has reached the center of the recess of the fixed cam 39, as shown in Fig. 5, the movement of the series of jacks and pressers being thus automatically stopped while the operator is removing and applying the shoes. Vhen the operator is ready for the progressive movement of the series ofjaeks and pressers to be resumed, he depressesa foot-lever, 4S, and thereby,through a lever, 47, depresses the pin 46, whereupon the springs 53 force the clutch 45 into engagement with the drivingpuiley. I do not limit myself to the employment of this particular stop-motion,butmayemployanyothersuitable automatic stop-motion whereby the progressive movement ofthe `jacks and pressers will be automatically arrested when each jack is depressed and any suitable devices whereby said progressive movement maybe resumed at thc will of the operator.

The sole-presser 1 is composed of a series of metallic frames or sections, 12, 13, and 14, open at their under sides and provided with flexible bottoms 26, composed of straps of leather or other suitable material secured by screws to the said metallic frames or sections, as clearly shown in Figs. 2 and3. I have shown the section 12 provided with two thicknesses of straps 26, one extending at right angles to the other, this section being longer than the others and formed to act on the fore part of'the sole, as shown in Fig. 2, so that a thicker and stronger flexible bottom is desirable for it than for the shorter sections 13 and 14, which are formed, respectively, to act on the heel and shank portions ofthe sole. The lower edges of the sections 12, 13, and 14 are curved to approximate the longitudinal'curvature ofthe bottom of the last, as shown in Fig. 2. rlhe straps or flexible pressingsurfaces 26 are sufficiently yielding to insure close conformation to all parts of the bottom of the last (or the shoe thereon) presented to the presser. To the back of the fore part and heel sections 12 13 are secured bosses 15 15, the upper surfaces of which are convex and are segments ofsphercs, the centers ot' which are located as close as possible to the pressingsurfaces of said sections. Said bosses bear against correspondiugly-formed concave seats 16 16, formed on aframe or holder, 6, and are connected to said holder by bolts 55 and washers 56, having convex upper surfaces, which are held loosely against the concave under surfaces of the bosses 15.by the bolts Holes are formed in the bosses 15 of considerably greater diameter than the bolts 55, so that said bosses and the sections 12 '13 attached thereto can tip in any desired direction, and thus conform to various longitudinal and transverse eurvatures of last-bottoms.

rlhe section 14 is provided with a convex rib, 17', formed on a block, 17, extending crosswise of the sole-presser, said rib being fitted in a correspondingly-cnrved socket in a block, 18, which is movable vertically, as hereinafter described, so that the section 14 can be depressed to bearon and hold the shank portion of the outer sole before the jack supporting the same is raised to press the fore part and heel portions of said sole against the presser.

IIO

When the section 14 is not so depressed, but is in operative position, as shown in Fig. 2, it is unyieldingly supported against upward pressure by the holder 18.

The rib 17 and socketed holder 18 permit the shank-section 14 to tip crosswise of the presser. The rib 17', like each of therbosses 15 15, has its center near the pressingsurface of the section to which it is attached, the'several centers, which are marked M11 inr Fig. 2, being in line with each other.

By the described arrangement, whereby the sections 12, 13, and 14 of the presser can tip in arcs having their centers as close as possible to the pressing surfaces of said sections, I enablesaid pressing-surfaces to conform to the usual variations in the shape of last bottoms without having such a bodily movement over or upon the sole as would tend to cause either pressing-surface to displace the sole when first brought in contact with it. In other Words, when either section is brought into relation with the corresponding portion of a last-bottom towhich such section is not already adjusted, the movement of the section whereby it is adjusted to the shape of the last-bottom is a tipping movement upon a center which is close to or on the pressing surface or" the section, and not a swinging or lateral movement.

tending to displace the sole on the bottom of the last, as it would be if the center of Said movement were remote from the pressing-surface.

The sections l2, 13, and 14 are preferably detachablysecured to the bosses 15 15 and ribbed block 17, so that said sections can be used interchangeably with others formed for `lasts of radically-different shape. To this end each section has a dovetail rib, 60, and said ribs are removably titted in the bosses l5 15 and block 17, as shown in Fig. 2.

AThe frame 6'is provided with a convex boss,

- 7, which is a segment of a sphere, and is held against a corresponding concave seat, 8, on a supporting frame or Ahead, 9, by a tubular bolt, 10,- passing through an orifice 'in said frame and secured to the latter by a nut, 58, and a washer, 11, supported by the head of said bolt and heldthereby against the concave under side ofthe boss 7, said washer having a convex upper surface which tits the under side of the boss. By this connection of the presser to the frame 9 the presser as a whole is permitted to tip in any direction, and thus furtheradapted to conform to various shapes and styles of lasts.

The frame 9 is vertically adjustable in guides 2l 21,forrned on the standard 5, and is-adj usted and held in different positions bya screw, 23, which works in a tapped socket in the upper portion of said frame, and is journaled in a yoke on the standard 5. Said screw has a hand-wheel, 24, whereby it may be rotated.

The vertical position ofthe presser can therefore be varied as the operator may desire.

As already stated, theshank-section 14 of the presser is capable of being depressed below the other sections, so that it may bear upon the shank of the outer'sole before the jack is raised. To this end the socketed block 18, which supports the shank-section 14, has a'rod, 19, which is passed through the tubular bolt 10, and is adapted to slide vertically in ysaid bolt, and is provided with a spring, 22, whereby it is normally depressed and caused topress the .shank -section 14 against the shank of a sole while the jack Von which the sole rests is depressed. The object of this arrangement is to enable the operator to secure the outer sole in its proper place on the/jack before the jack commences its forward and upward movement and to obviate the necessity ofthe operator holding the sole upon the jack while the latter is rising and presenting the sole to the presser.

The section. 14 Ymay be held elevated, as shown in Figs. 2 and 3, until the operator has jacked the shoe and placed the outer sole thereon by a camshaped collar, 20, adapted to rotate on the rod 19 and bearing on a xed cam-shaped collar, 21, through which the rod passes. When the collar 20 is turned to the position shown in Fig. 2, it rides up the in cline of the tiXed collar 2l and raises the rod 19 and the shank-section 14. When the operator has placed the sole in position on thejack, he turns the collar 2() so that it rides down the incline of the collar 21 and carries down the rod 19 and the section 14. provide a spring, S, whereby the collar 2O is automatically turned to the position shown in Figs. 2 and 3 when the shanksection 14 is raised, so that the said section is automatically secured in the raised position shown until the operator is ready to depress it.

It is obvious that the improved presser herein dcscribed may be used in a machine employing but one presser and onejack. It is also evident that the sole may be conformed to thebottom of the last bya movement of the' presser toward thejack instead of the reverse.

My invention is not limited to the details of construction herein described, and the same I prefer to A ICO IlO

maybe variously moditiedwithout departing from the spirit of the invention.

In an organized sole-laying machine having a series ofjaeks mounted on a rotary carrier .and automatically raised and depressed, as

herein described, I may use any suitably-constructed sole-pressers, my invention not being limitedto the construction shown.

It is essential that the pressers be con- Structed to conform to variously-shaped lasts;
